Google Whitepaper Flags 2029 Quantum Deadline, Zyskind Warns of Retroactive Decryption Risk
A Google whitepaper sets a 2029 target for migrating away from today’s cryptography, warning that quantum advances could undermine widely used schemes. Computer scientist Guy Zyskind says blockchains should accelerate post-quantum moves such as lattice-based cryptography and encrypted mempools, but adds that upgrades cannot prevent quantum adversaries from decrypting historical on-chain data later.
